Typically found in various aerial, terrestrial, and aquatic environments.

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

Epaulard

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).

Blue-tailed Emerald

A small, jewel-like hummingbird named for the brilliant blue-green iridescence of the tail feathers, male blue-tailed emeralds display glittering green plumage throughout with a contrasting deep blue-green forked tail. Found in lowland tropical forest edges, savannas, and gardens from Venezuela and Colombia east to Trinidad and south to Bolivia and Brazil. They are common in disturbed and secondary habitats, making them relatively resilient to habitat modification compared to more specialized hummingbirds.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
